Samples of species close to from China and Brazil are studied, and is confirmed as a species complex including nine species. Five known species (, s.s., "", and ) and four new species (, , and ) in the complex are recognized based on morphological characteristics, molecular evidence, and geographic distribution. Sequences of eight species of the complex were included in the phylogenetic analyses because lacks molecular data. The phylogenetic analyses were performed by a combined sequence dataset of the internal transcribed spacer (ITS) and the partial nuclear large subunit rDNA (nLSU), and a combined sequence dataset of the ITS, partial nLSU, the small subunit mitochondrial rRNA gene (mtSSU), the translation elongation factor 1-α (TEF1), the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2). The eight species formed eight independent lineages with robust support in phylogenies based on both datasets. Illustrated description of the six species including s.s., "" and four new species, and discussions with their related species, are provided. A table of the comparison of the important characteristics of nine species in the complex and a key to the whitish species in s.s. are provided.
对来自中国和巴西的近 物种样本进行了研究，并确认 为一个包含九个物种的复合物种。根据形态特征、分子证据和地理分布，识别出该复合物种中的五个已知物种（ 、 狭义种、 、 和 ）以及四个新物种（ 、 、 和 ）。由于 缺乏分子数据，该复合物种的八个物种的序列被纳入系统发育分析。系统发育分析通过内部转录间隔区（ITS）和部分核大亚基 rDNA（nLSU）的联合序列数据集，以及 ITS、部分 nLSU、小亚基线粒体 rRNA 基因（mtSSU）、翻译延伸因子 1-α（TEF1）、RNA 聚合酶 II 的最大和第二大亚基（RPB1 和 RPB2）的联合序列数据集进行。基于这两个数据集的系统发育树中，这八个物种形成了八个得到有力支持的独立谱系。提供了包括 狭义种、 以及四个新物种在内的六个物种的图示描述，以及与它们相关物种的讨论。提供了 复合物种中九个物种重要特征的比较表以及 狭义种中白色物种的检索表。
